Subject: [lxc-dev] [patch -lxc 1/3] change clone_flags type to u64

This is a preliminary patch changing the clone_flags type to 64bits
for all the routines called by do_fork(). 

It prepares ground for the next patch which introduces an enhanced 
version of clone() supporting 64bits flags.

This is work in progress. All conversions might not be done yet.
